@Jamesh291183 I see the same behavior. I initially thought it was just because of mobile, but if you click on any of the visual elements and expand the view (or blow it up by clicking on the square with arrow) then it fills the entire gray area with the visual. So, I don't know if it's a width issue, or something that could be scaled better. @RomiK any input?
Mobile: and Mobile with zoom in
Can we request a feature that would let you "Launch in PowerBI App" or something like that then? This would let us design a mobile layout and then people could use it in the mobile app if they were on a phone and it wasn't rendering properly in a browser. Plus, it would bring people into your app!
